For the specific testcase we arrive with an anonymous SSA_NAME so that SSA_NAME_VAR becomes NULL and we crash. 2021-02-24 Richard Biener <rguent...@suse.de> PR c/99224 * builtins.c (fold_builtin_next_arg): Avoid NULL arg. * gcc.dg/pr99224.c: New testcase. (cherry picked from commit 084963dcaca2f0836366fdb001561e29ecbfb483)
